Unformatted text preview: A 66 - 80 B 51 - 65 C 40 - 50 D 0 - 39 F Now we turn to the most oft asked question at the end of a semester: WHAT DO I NEED TO GET ON THE FINAL? You know your midterm average, and the grade you want to shoot for. Calculate the (percentage) grade you need to get on the final to reach your goal. For example, consider a student who scored 31/40 [77.5 percent] on Exam I and 150/200 [75 percent] on Exam II. Her midterm average is MID = (77.5 + 75)/2 = 76.25. She wants to make an “A,” to raise her course average to at least 81. So she solves for FIN: 81 = 0.60 × 76.25 + 0.40 × FIN if FIN = 88.13 If she scores 88 percent on the Final she is guaranteed an “A” in the course. She can do a similar calculation to determine as long she scores at least 51 percent she will still have her “B.”...
